V IMPROVEMENT IN GRATES.

Specification forming part of Letters Patent No. 40.34 I, dated October20, 1863.

To all whom, it may concern:

Be it known that 1, SAMUEL J. KELLY, of Pemberton, in the county ofBurlington and State of New Jersey, have invented a certain new anduseful Improvement in Stoves and other Grates; and I do hereby declarethe following to be a full and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figure 1 is a front end elevation of myimproved grate. Fig. 2 is a plan thereof, showing the movable portion ofthe grate partially withdrawn. Fig. 3 is a vertical section of a portionof the same, taken in the line was, Fig. 2.

bimilar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in a grate of peculiar and simple construction,designed to facilitate the removal of cinders, ashes, and other refuse.

To enable others skilled in the art to which my invention appertains tofully understand and use the same, I will proceed to describe itsconstruction and operation.

In the accompanying illustration of my im proved grate A A A representseparate castiron or other metallic plates, formed with flanges a a a attop, which are designed to rest upon a horizontal rib permanentlylocated within the stove at the front thereof, and thus to constitutethe ineans for sustaining this part of the grate. To these plates areattached at suitable regular intervals the gratebars B, the lower frontportions of which are curved in the usual manner. At their oppositehorizontal ends the bars, which are attached to the plates A A, aresecured in corresponding notches formed in a horizontal bar, (J,extending from end to end at the back of the grate. The form of this baris clearly shown in Fig. 2. Those portions of it occupied by the bars ofthe plates A A, are of uniform dimension. At the termination of theseportions, where it is intended to insert the bar D, to which thegrate-bars of the plate A are attached, the bar 0 is formed with convering or oblique rests or projections E E, upon which the bar D is to besupported, the ends of the latter being formed to correspond therewith,as shown by dotted lines in Fig. 2.

I'Vheu it is desired to remove the contents of the grate for the purposeof rebuilding the fire, this may be expeditiously performed by merelyplacing the hand beneath the central section, A a. pressing it slightlyupward and then drawing it forward a little. Thus a sufficient space ismade to permit the passage of cinders, ashes, or other refuse, most ofwhich are precipitated into the ash-pan below by the movement of thesection A a.

I am aware that it is not new to construct grates with one or moreremovable bars for the purpose of facilitating the clearing of thegrate. One among many examples of this is seen in the patent of Wm. L.McDowell, granted April 28, 1863.

My invention is a new and improved construction of the parts to effectthe above object. Its superiority over that of McDowell, above referredto, consists in providing for the removal of a section of the front andbottom of the grate, the aperture thus formed extending completelyaround from the top to the extreme rear and lower part without theintervention of any transverse bars to interfere with the freedom of thedischarge.

Having thus described my, invention, the following is what I claim asnew therein and desire to secure by Letters Patent:

In combination with the plates A A a a, grate-bars B, and bar 0, themovable section A B, supported at front by means of the flange a, and atback by the beveled bar D, resting in a corresponding recess, E E, inthe bar (3, when the said movable section extends completely around fromthe front and top to the lower and rear part of the grate, and all theparts are constructed and arranged in the manner and for the purposesspecified.

SAMUEL J. KELLY.
